small flexible light to probe in the spark plug hole. I have several expensive one's, but Farm and Fleet had the "Lisle" brand for about ten bucks that will do. Go to #1 at TDC and then rotate a little more so the piston is down and easier to see the top If it is just a flat top with the 4 little eyebrows it is not too likely to be a 410 or 428, as they had a small dish in the center. This would indicate a 360 truck or a 390 car piston. Since you indicated a 3.98 stroke, I doubt you could of been off that far to be a 360. If you pull the pan, a 1U stamping would indeed be a 3.98 stroke. There are a number of 3.78 stroke #'s, so I would have to wait till you pulled the pan. |
